Plug-in and screw-in temperature sensors

A plug-in and screw-in temperature sensor is a device that is used to measure the temperature in various applications. It consists of a metal rod or probe that is inserted or screwed into an object or liquid to measure the temperature.

An insertion temperature sensor is normally used to measure the temperature in solid objects such as food, soil or other materials. The probe is inserted directly into the object to measure the temperature.

A screw-in temperature sensor, on the other hand, is normally used to measure the temperature of liquids or gases. The probe is screwed into a thread or opening to measure the temperature of the liquid or gas.

Both types of temperature sensors are used in various industries and applications, such as in the food industry, in heating, ventilation and air conditioning technology, in the automotive industry and in process automation.

A plug-in or screw-in temperature sensor consists of a metal tube or rod that is installed in a housing. The housing is either inserted into a hole or screwed into a thread to fix the sensor in the desired position.

The sensor is equipped with a thermocouple or a resistance thermometer. With a thermocouple, the temperature difference between the two metal connections within the sensor generates an electrical voltage that is proportional to the temperature. With a resistance thermometer, the electrical resistance of the sensor changes depending on the temperature.

The electrical measured variable of the sensor is transmitted to a measuring device or a control unit via cables or wires. The measured temperature is displayed or processed there.

Push-in and screw-in temperature sensors are available in various designs and materials to meet the requirements of different applications. They are frequently used in industry, in heating and air conditioning systems, in the food industry and in building automation.

6. Plug-in sensor with infrared sensor: These sensors use an infrared sensor to measure the surface temperature of an object without touching it. They are ideal for applications where non-contact measurement is required.

These types of insertion and screw-in temperature sensors can be selected depending on the application and the required measuring accuracy.

Push-in and screw-in temperature sensors are used in industrial applications to measure the temperature in various processes and systems. These sensors are normally installed in pipelines, containers, tanks and other industrial equipment.

Insertion temperature sensors are inserted directly into a hole or bore drilled into the material whose temperature is to be measured. The sensor is then fixed in place with a screw or other fixing method to ensure an accurate and reliable measurement. Push-in temperature sensors are ideal for applications where direct contact measurement is required, such as in liquids, bulk solids or gaseous media.

Screw-in temperature sensors, on the other hand, are screwed directly into a thread in a pipe or tank. The sensor is normally fitted with a sealing ring to prevent leakage. Screw-in temperature sensors are well suited for applications where temperature measurement is required in a pipe or a closed system.

Both types of temperature sensors can be used in various industrial sectors, such as the chemical, petrochemical, food and beverage, power generation, pharmaceutical and many others. They enable precise and accurate temperature measurement to ensure process control, quality assurance and safety in industrial plants.

The accuracy of insertion and screw-in temperature sensors is ensured by various factors:

1. Calibration: Before delivery, the sensors are calibrated to ensure that they measure the correct temperature. They are compared with known reference temperatures and adjusted accordingly.

2. Material quality: High quality materials are used to ensure that the sensor can accurately measure the temperature. This includes both the housing and the sensors inside.

3. Construction: The design of the sensor is such that it enables the most accurate temperature measurement possible. This can be achieved, for example, by optimally positioning the sensor in the housing.

4. Environmental factors: The accuracy can also be influenced by external factors such as vibrations, humidity or electrical interference. Appropriate protective measures are therefore taken to ensure that the sensor operates under the intended conditions.

5. Monitoring and maintenance: Regular inspection and maintenance of temperature sensors can help maintain their accuracy over time. This includes regular calibration and, if necessary, the replacement of worn or damaged parts.

These measures ensure that insertion and screw-in temperature sensors offer high accuracy and reliability in temperature measurement.

The following factors should be taken into account when selecting a suitable insertion or screw-in temperature sensor:

4. Protection type: Depending on the environment in which the sensor is used, a certain degree of protection may be required. This can be protection against moisture, dust or other environmental influences, for example.

5. Mounting type: There are different types of plug-in and screw-in temperature sensors, such as screw-in sensors with a thread or plug-in sensors with a sleeve. The installation method should be adapted to the specific requirements of the application.

6. Material: The material of the sensor is important, as it must withstand certain conditions depending on the application. For example, a stainless steel sensor may be suitable for applications with high temperatures or corrosive environments.

7. Cable length: Depending on the application, the length of the cable may be important to ensure that the sensor can be connected to the desired position.

8. Calibration: Depending on the application, it may be necessary for the sensor to be calibrated. This is particularly important when there are high accuracy requirements.

It is important to consider the specific requirements of the application and, if necessary, consult experts or manufacturers to select a suitable insertion or screw-in temperature sensor.
